Heat Flows on Time-dependent Metric Measure Spaces
(2018-04-26)
We consider time-dependent metric measure spaces evolving as a super Ricci flow in the sense of Sturm. We haracterize these by means of the (time-dependent) heat flow. We establish equivalence of super Ricci flows, gradient ...
EPR distance measurements using triaryl methyl radicals and EPR investigation of electron transfer processes in organic radicals
(2018-04-17)
EPR is a valuable tool for the investigation of biological structures. Most EPR-based distance measurements rely on the site directed spin labeling of the investigated biomolecule, since most biomolecular structures do not ...
Nucleon-nucleon scattering process in Lattice Chiral Effective Field Theory approach up to next-to-next-to-next-to-leading order
(2018-04-23)
We carry out a comprehensive analysis of the neutron-proton interaction up to the third order in the scheme of chiral effective field theory on the lattice. The complete two-pion exchange potential is taken into account ...
Exploration of advanced CMOS technologies for new pixel detector concepts in High Energy Physics
(2018-04-19)
This thesis presents the author’s original concepts for the development of radiation hard monolithic pixel sensors that can replace hybrid pixel sensors in high energy physics experiments. It presents one of the first ...
The Physics and Chemistry of Oxygen-rich Circumstellar Envelopes as Traced by Simple Molecules
(2018-04-17)
The physics and chemistry of the circumstellar envelopes (CSEs) of evolved stars are not fully understood despite decades of research. This thesis addresses two issues in the study of the CSEs of oxygen-rich (O-rich) evolved ......
Measurements of differential t-channel single top-quark production cross-sections in proton–proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS detector
(2018-03-28)
Proton-proton collision data at a centre-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, corresponding to an integrated luminosity of 20.2 fb-1, are used to measure absolute and normalised ...
Ethologische Untersuchungen der Wahrnehmung von Oberflächenwellen des Wassers bei Krokodilen
(2018-03-23)
Krokodile nutzen zum Beutefang neben visuellen, auditorischen und olfaktorischen Reizen auch Oberflächenwellen des Wassers, die sie mit ihren Integumentary Sensory Organs (ISOs) wahrnehmen. ISOs befinden sich hauptsächlich ...
Molecular Mechanisms in the Unconventional Secretion of Insulin-Degrading Enzyme
(2018-04-12)
Extracellular deposition of amyloid-ß (Aß) plaques in the brain, a hallmark of Alzheimer’s disease (AD), results from an imbalance between production and clearance of the peptide. Insulin-degrading enzyme (IDE) is one of ...
Investigations into the DNP characteristics of electron and proton irradiated polyethylene and polypropylene
(2018-03-06)
To achieve a significant enhancement of the nuclear polarisation of solid state target materials one must use the method of dynamic nuclear polarisation. This necessitates unpaired electrons, that can be created as ...
Modulation Spectroscopy of Ultracold Atoms in Optical Lattices
(2018-03-12)
In the past fifteen years ultracold atoms confined to optical lattices, which are artificial crystals of light, have proven to be powerful tools in the study of strongly correlated many-body systems widely known from a ......
